Feature(may vary by option.)

●ADS115 is an AD converter featuring 16-bit resolution, 4-channel single-action and 2-channel differential input
●Arduino analog input resolution is 10 bit, so it can only be digitized in 1024 stages. The ADS115 can be digitized with 16 bit (2^16=65536 levels). You can measure the voltage with greater accuracy than the Arduino single one
●Can be inputed with 4 singles or 2 differential channels. Differential input reduces the number of channels to 2 channels, but differential is more noise and stable to read voltage
●I2C interface provides digital output of measurement values. Easily measure with microcontrollers like Arduino or Raspberry Pi
●You can change the slave address to 4 different types by connecting the ADDR terminal. With 4 ADS115, you can measure the voltage of 16 channels

Differential InputDifferential Input

You can choose from the library of measuring methods with a single 4 channel or 2 differential channels.In general, differential people are noise-resistant and stable to read voltage, but since two input terminals are used in one channel, the number of input channels is reduced by 2 channels.
